ROBERT H. HENDERSON AND JOHN G. HENDERSON, OF CHICAGO, ILLINOIS.
INSULATING-KNOB FOR ELECTRIC-LIGHT WIRING.
SPECIFICATION forming part of Letters Patent No. 660,271, dated October 23, 1900.
Application filed December 10, 1897. Serial No. 661,467- (No model.)
To all whom it may concern.-
Be it known that we, ROBERT H. HENDER= soN and JOHN G. HENDERSON, of the city of Chicago, in the State of Illinois, have invented a new and useful Improvement in Insulating-Knobs for Electric-Light Wiring, which is made and used substantially as set forth hereinafter.
The object of this invention is to enable the operator to run electric-light wires on insulating-knobs in a firm and substantial manner without tie-wires.
To enable others skilled in the art to use our invention, we proceedto describe its construction and operation by means of the accompanying drawings, in which-'- Figures land 2 illustrate the manner of stringing the wires on the knobs. Fig. 3 is a side elevation of a knob.
Similar letters refer to similar parts in each figure.
This insulating-knob is constructed like an ordinary insulating-knob, with the addition of a hook or horn a, curved over from its outer end and forming a cavity b,large enough to receive the required wire d, Fig. 1. When the end of the wire 0, Fig. 1, is placed in the cavity 19, under the hook a, and the wire dis wrapped around the knob in the groove 6, it is impossible to pull it out by drawing on the line d or to unfasten it by taking hold of the end 0, Fig. l, and when the wire is run to the next knob and wound around and placed in the cavity 19, under the hook, as shown in Fig. 2, the turning of the knob tightens the line d and fastens the wire, so that the end 0, Figs. 1 and 2,0an be run at any angle orin any direction, thus setting forth these two distinctive features of this knobthat the ends are held so that they cannot be unfastened and that theturning of the knob tightens the line. No knobs previously used have had either of these essential qualifications. All of them that have any way of holding the wire hold it in such manner that it can be unfastened from the knob by taking hold of the end of the wire, and none of them have the other feature of tightening the wire by turning the knob.
That we claim as our invention, and dc sire to secure by Letters Patent, is-
1. An insulating-knob with a groove for a wire like an ordinary knob, With a hook curved over from its outer end, forming a cavity underneath large enough to receive the required wire, in such proximity to the groove that when the end of a wire is placed underneath this hook and the wire wrapped around the knob in the groove it effectually shuts in the end of the wire, so that it cannot be pulled out.
2. An insulated knob with a groove for a wire like an ordinary knob with a hook curved over from its outer end forming a cavity underneath, large enough to receive the required Wire, in such proximity to the groove that when a wire is brought from another knob and wrapped around this knob and placed under the hook it holds the wire so it cannot slip, while the knob is being turned to tighten up the line-wire between the knobs.
